Biosynthesis of indicaxanthin in opuntia ficus-indica fruits

Phytochemistry, 1972
Abstract The result of the incorporation of doubly labelled tyrosine into indicaxanthin in the fruits of Opuntia ficus-indica shows that the dihydropyridine moiety of the pigment originates from dopa by extradiol cleavage of the aromatic ring.

Composition and properties of Opuntia ficus-indica mucilage

Phytochemistry, 1981
Abstract The mucilage isolated from Opuntia is shown to contain arabinose, galactose, galacturonic acid, rhamnose and xylose. It has a uronic acid content of ca 10% and a MW of 4.3 × 106. It equilibrates to 175% of its dry wt at 100% relative humidity. Its possible role in the physiology of the plant is discussed.

Antileishmanial activity of Opuntia ficus-indica fractions

Biomedicine & Preventive Nutrition, 2014
Abstract Cladodes and fruits of Opuntia ficus-indica are used in traditional medicine for the treatment of abscess and skin inflammation. It was therefore interesting to assess whether an antileishmanial activity could be associated to skin healing. This study reports on the antileishmanial activity of Opuntia ficus-indica extracts from cladodes and ...

Characterization and transformation of the Opuntia ficus indica fruits

Journal of Food Measurement and Characterization, 2018
Opuntia ficus indica fruits have been associated with health effects, due to their protective actions against oxidation. Nevertheless, few studies about processing of Opuntia fruits are available’; therefore, we studied the pulp characteristics and processing of a local variety, for producing beverage nectars. The pulp had an average pH of 5.64, 13.47 °

Methylation analysis of the mucilage of Opuntia ficus-indica

Carbohydrate Research, 1981
Abstract The mucilage of Opuntia ficus-indica and a partially degraded mucilage have been investigated by methylation analysis and periodate oxidation. The results show that the mucilage is composed of 1,4-α- D -galactopyranosyluronic acid and 1,2-β- L - rhamnopyranosyl residues to which are attached short chains of 1,6-β- D -galacto-pyranosyl ...

Biophysical properties of Opuntia ficus-indica mucilage

Phytochemistry, 1980
Abstract The purified mucilage from Opuntia ficus-indica is a high MW polysaccharide which behaves as a polyelectrolyte. Viscosity of its solution is dependent on the Ca2+ ion concentration and on pH, being greatest at alkaline pH. The sedimentation coefficient was dependent on concentration. The molecule had an estimated axial ratio of 256 in water,

By-Products of Opuntia ficus-indica as a Source of Antioxidant Dietary Fiber

Plant Foods for Human Nutrition, 2010
Dietary fiber and bioactive compounds are widely used as functional ingredients in processed foods. The market in this field is competitive and the development of new types of quality ingredients for the food industry is on the rise. Opuntia ficus-indica (cactus pear) produces edible tender stems (cladodes) and fruits with a high nutritional value in ...

Secondary metabolites from Opuntia ficus-indica var. saboten

Phytochemistry, 2006
A butanol fraction, from the methanolic extract of Opuntia ficus-indica var. saboten, on purification either by preparative TLC or reversed phase HPLC, yielded three chemical components: isorhamnetin 3-O-(6''-O-E-feruloyl)neohesperidoside (1), (6R)-9,10-dihydroxy-4,7-megastigmadien-3-one-9-O-beta-D-glucopyranoside (2) and (6S)-9,10-dihydroxy-4,7 ...
